SClSSORS-GRINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 622,012, dated March 28, .1899. Application filed December 18, 1897. Serial No. 6G2 412- (No infidel.)

To all whom, it may concern:

Be it known that I, EMIL NEWQUIST, of Carlton, Carlton county,Minnesota,have invented certain Improvements in Scissors-Grinding Attachments for Sewing-Machines, of which the following is a specification.

My invention is a device for sharpening scissors, 850., adapted to be detachably secured to a sewing-machine and to be actuated by the operating-belt of the machine.

To this end my invention consists in the specific construction and combination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view showing my device attachedto the table of a sewing-machine, and Fig. 2 is a partial section of the machine with my device attached thereto.

In the drawings, A represents the table of the sewing-machine, upon which is mounted the ordinary frame 2, provided with a flywheel 3.

4 represents the operating-belt of the machine.

My improved device B consists of a block 5, preferably of wood, provided with upwardly-projecting sides 6, in which is journaled the shaft '7, carrying the emery-wheel 8, adapted to be actuated by the operating-belt 4. Upon the under side of the block 5 is secured the rubber 10 to prevent marring of the machine-table. The block 5 is formed with in the drawings.

. in the arm 15, having pivotal connection with the frame of the sewing-machine. The running of the machine in the ordinary manner will cause the emery-wheel to be rotated. The scissors to be sharpened are then placed against the emery-wheel, being supported by the support 13.

The great advantage of my invention over the ordinary hand-sharpeners or fixed attachments will be apparent. With my construction it can be quickly and easily applied to the machine and detached as soon as used without injury to the machine.

What I claim as new, and desire to secure by Letters Patent, is

A grinding attachment for sewing machines consisting of a grinding-wheel adapted to be actuated by the machine-belt, the block or base upon which said wheel is mounted provided with a groove and the spring-clamp detachably securing said attachment'to the machine-table, one side of said clamp being received by said groove.

In testimony whereof I affix my signature in presenceof two witnesses.

EMIL NEWQUIST.
